I have used this Kitchen Calc even before there were apps! Absolutely the best out there, bar none.

I grabbed the wrong measuring cup 1/3, when I was supposed to use 3/4. and had to figure out what was left to add for the sugar. 3/4 cup minus 1/3 cup = 6.5 tblspoons. Saved me from throwing out the whole recipe!

I'm a culinary student so I'm always multiplying and converting units- this app does it all for me.

Im a chef and I've tried at least 3 of the other kitchen calculator types and they don't even begin to compare. THIS ONE is sooo easy and straightforward to use! I've had their real hand held kitchen calc for years since I was in culinary school and they're invaluable for recipe development and scaling recipes! And they finally they came out with this app!!(I've been emailing them for 3 years asking for it!)) Don't waste your time with the other ones. Theyre all so cartoony and they take like 4 steps/ screens to complete one calculation. This one is so simple. Honestly couldn't live this app more!!!! --Chef Amy Jurist
